CONDENSER.

Application filed October 31, 1925, Serial No. 66,053, and in Great Britain November 10, 1924.

This invention relates to heat interchange apparatus of the kind in which the medium undergoing treatment is caused to fiow in a sinuous or tortuous path around a series of 5 plates or bafiles, and has for. its chief object the provision of an improved form of apparatus of this character having provided a relatively large heat interchange area or surface and which is constructed of a relal0. tively few standardized or interchangeable parts so as to permit the apparatus to be easily and quickly assembled or dismantled for replacements or repairs.

The invention may be employed in connection with apparatus for heating, cooling or condensing fluids, and is particularly intended for use in condensing oil gases or vapours.

Heretofor the aforesaid plates or bafiles around whi dh the medium flows have been disposed within circular tubes, and such tubes, in cases where they are superimposed or arranged side by side, and when employed for the purpose of condensing fluids, possess the disadvantage that the condensate after treatment drains of! at the end of each tube, and has therefore to be collected at a large number of points. This drawback is overcome in the present invention by causing the medium to flow in a sinuous or tortuous path around baflle plates which are of elongated form and are removably disposed within a tubular member or conduit or rectangular or flattened construction, that is to say, a conduit having a height which 1s large in relation to its width when it is disosed within an outer casing 0r mounted etween tube sheets.

In order that the said invention may be clearly understood and readily carriedinto effect, the same will now be described more fully with reference to the=accompanying drawings in which Figure 1 is a part sectional elevation, the

section being taken on the line 1-1 of Figure 2 showing one embodiment of the invention. p.

Figures 5 and 6 are partlydiagrammatic sectional plan views showing a further embodiment of the invention.

e is an outer rectangular casing containing a series of rectangular or flattened tubular members or conduits e, 6 extending longitudinally t-herethrough and having their ends secured in tube sheets a and 'b so as to prevent any possibility of the fluid passing through the tubular members or conduits mixing with that which passes around the condults. The conduits e, e are formed or arranged so that their height is large in tudinally of and extending beyond the ends a of the conduitseach pair of rods being connected by abar- 6. The baflle plates are preferably L-shaped and are arranged within the conduits so that one edge of each angle plate bears against onewall of the conduit, while the other edge projects towards the centre thereof and isconnectedto the rods 6 6 so that an entire set of battle plates can simultaneously be withdrawn from the apparatus for cleaning or other purposes.

buitable openings 6 0 are provided adjacent opposite ends of the outer casing e for admitting and withdrawing fluid from the space around the conduit 6. For the circulation of the fluid which is caused to pass through the conduits e the tube sheet a; is connected to a' casing 6 provided with openings e and 0 while the tube sheet 6 is con nected to another casingd provided with opening 0 and 6 I A The use of conduits of flattened construc tion instead of circular casings or tubes, has the advantage that a large number of such conduits canbe located within an outer surrounding casing in a very compact manner, while the use of long platesor baflies disposed within said conduits has the further advantaae that in the case of a, condenser the condensate flows down the plates of baflles to the bottom of each conduit so that it can conveniently be removed from one end thereof, or at one or more points along the lower side of the casing.

It will be observed that the apparatus is of simple construction and is formed of a relatively few standardised or interchangeable parts so as to facilitate assembly or dismantling for replacements or repairs.

hen employing the apparatus illustrated for the condensation of oil gases or vapours a cooling medium is admitted to spaces around the conduits e through the opening a and withdrawn through the opening 6 The gases or vapours which are to be condensed are admitted to the outer casing through an opening e and before entering the aforesaid conduits e, a they pass through the chamber e located at the entrance thereto. This chamber contains a number of depending bafile plates 6 e and on the gases striking the said baffles a e the heavier oils are preci itated and can be led away from the chain er 6 through the opening e". The uncondensed vapours thereafter enter the conduits e, e and owing to the arrangement of the baffle plates 0 the gases are compelled to follow a sinuous path in passing from end to end thereof. The condensed oils leave the apparatus through the opening e while the uncondensed vapours leave the apparatus through the opening a The conduits e, e may, if desired, be divided into sections by means of bafiie plates such as e which extend from side to side thereof and project upwardly from the base thereof so as to leave at the top a space f which allows the vapours to pass but separates the condensate in one zone from the condensate in other zones, so that the liquid oils can be collected separately from each of the same zones. The apparatus is provided at one end with a cleaning door a, and by opening the same and withdrawing by means of the rods e the angle plates of any one conduit the same can readily be cleaned without disturbing the other conduits. Referring to Figures 5 and 6, F is a conduit of flattened, construction similar to one of the rectangular conduits 6 shown at Figures 1 to 4 and a plurality of which may replace the conduits 6 within the outer casing e, the conduit F containing a number of channel or U shaped members F, F, which may either be loosely located within the conduit or which may be riveted together as shown at F The U-shaped members F, F, are staggered relatively to one another as shown and are mounted upon a rod G of oblong cross section, the rod being passed through ova], oblong or elongated slots F, F, in each of the baflle plates F. By turning the rod G into the position shown at Figure 5 the channel shaped battles F are tightly pressed against the casing F, thus serving to produce an efficient heat intcrchange between the medium undergoing treatment and the heating or cooling medium applied externally to the casing F. When, however, it is desired to remove the battles for cleaning or other purposes the rod G is turned into the position shown at Figure (5 thus bringing the members F out of contact with the walls of the casing F and allowing the same to be removed for cleaning and other purposes.

Although the various features of the invention have been more particularly described in connection with the treatment of vapours derived from the distillation of carbonaceous materials, it is to be understood that, where applicable, they may be employed for the treatment of other gases, vapours or materials.

\Vhat I claim and desire to secure by Letters Patent of the United States is 1.
